IMPROVEMENT IN SOLDER ING-FURNACES.

Specification forming part of Letters Patent No. 143,126, datedSeptember 23, 1873; application filed April 30, 1873.

To all whom it may concern:

Be it known that I, J USTUS DAY, of Holley,

in the county of Orleans-and State of New York, have invented a certainnew and useful Improvement in Tinmens Fire-Potsyand I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same.

My invention consists in combining with a tinmans fire'pot anarrangement of tubes and slides, which are adjustable up and down,andserve to receive the irons to be heated, as hereinafter fully described.

In the drawings, Figure 1 is a perspective view; Fig. 2, a verticalsection of the fire-pot through one of the adjustable tubes 5 Fig. 3, across-section through the grate.

A represents the fire-pot or furnace, in which is a magazine orfuel-chamber, D, similar to that in a base-burning stove. B is thegrate, which rests on lugs or ledges a a, Fig. 3, and has a shakingmotion,in and out, to remove ashes. (l O are tubes, resting on slides bb, and extending through the fire-pot, so as to project at each end, asshown. The ends are open to receive the soldering-irons, but may becovered by caps 00, when not in use. If desired, a portion of the tubesmay be made short, not extending through the whole furnace, as shown inthe center in Fig. l; but the inner end of the tube in that case isclosed, and it serves to receive soldering-irons that have a hook orbend. The slides b b adjust up and down in ways 01 d, and they areprovided with a series of holes, f f, through which passes a pin, 9, bywhich the adjustment is made higher or lower.

The tubes receive the irons and impart the necessary heat withoutbringing them in contact with ashes, which clogs and impedes them inapplying solder, and it renders the wiping of the irons unnecessary. Theadjustment of the tubes higher or lower graduates the heat applied tothe irons, as may be necessary, and also adapts the same to the intensity of the fire in the fire-pot. The slides at the same time coverthe slots in which the tubes slide.

By the use of this invention ordinary hard coal may be used in place ofcharcoal, which has generally been employed. The tubes shield the ironsfrom the action of the sulphur which forms one element of the coal.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination, with the firepot A, of the tubes 0 O and slides 12 b,when arranged for vertical adjustment, in the manner and for the purposespecified.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

J USTUS DAY.
